In her recent autobiography - Big, Beautiful And Sexy - Casey Donovan shocked the country with revelations of her six-year relationship with a made-up man and her subsequent sex addiction.

But she is getting back to what she really loves, posting photos on Instagram of herself rehearsing in the lead-up to the World Of Music, Arts And Dance (WOMAD) festival.

The 25-year-old singer will be performing at WOMAD in New Zealand this week as part of the Boomerang Project, which features artists from Scotland, New Zealand, and Australia.

Back to business: Casey Donovan is in rehearsals for a music festival in New Zealand this week and seemed to be having a great time, despite the recent attention on her unhappy private life over the past few years

Casey, who shot to fame as winner of Australian Idol in 2004, posted the cute photos and revealed a daggy sense of humour that has not been dampened by the recent attention on her troubled past.

One of her Instagram pictures featured a montage of five different photos from her day.

‘Why not put together a picture montage of my day whilst waiting for an interview, I'll walk you through it,’ Casey told fans in the caption.
